The paper presents the results of a study of the effect of stepped annealing on the microstructure, mechanical properties and electrical conductivity of longish rods Ø5 mm and wire Ø 0.7 - 1 mm made of aluminum alloys containing 0.13 % - 0.21 % zirconium, 0.40 % - 0.60 % cerium, 0.2 % - 0.3 % lanthanum and 0.19 % - 0.68 % iron, produced by ingotless rolling-extrusion (IRE) and drawing. The possibility of achieving a level of strength of a conductor wire of 172 - 179 MPa, a specific electrical resistance of 0.0291 - 0.0300 Ohm-mm2/m, and elongation to failure of 1.5 % - 3 % with relatively small additions of zirconium, cerium, and lanthanum in the alloy due to an increase in the content of iron, the choice of deformation and heat treatment parameters. The structure of the wire grain structure was studied after IRE, drawing and stepped annealing 350ºС, 40 h - 440ºС, 20 h at different stages of drawing. The research was supported by a grant from the Russian Science Foundation No 22-79-00108, https://rscf.ru/project/22-79-00108/.
